Claims.

This invention relates to improvements in a mechanism for stretching fur scarves and pelts, and it consists in the novel features which are hereinafter described. I I

One of the objectsof my invention is to provide a mechanical means for increasing the length of a fur scarf or pelt, either raw or nished, beyond the limit which may be attained by hand stretching as at present.

Another object is to have the fur scarf or pelt clamped at one of its ends and fastened at its other end to one end of a bar and thereupon to apply an intensified force to the other end of the bar and provide a means to prevent overhauling of the said force, whereby to stretch the pelt or the fur scarf to a permanent elongation of the same. o

A further object is to improve the quality of the fur by the above described process.

A still other object 'is to have my mechanism for stretching fur scarves and pelts relatively simple, compact, durable and inexpensive.

Other objects and advantages will hereinafter appear.

I attain these objects by the mechanism which is illustrated in the accompanying drawing or by any mechanical equivalent or obvious modication of the same. n

In the drawing Fig. 1 is a fragmentary longitudinal vertical section of my mechanism, showing some parts in elevation; Fig. 2 is a crosssection on the line 2-2 of Fig. 1, looking in the direction of the arrows; Fig. 3 is a cross-section on the line 3-3 of Fig. 1, looking in the direction of the arrows; and Fig. 4 is a sectional plan on the line 4-4 of Fig. 2, looking in the dilrection of the arrows, drawn to a smaller scale than the other figures of the drawing.

Fig. 5 is a detail in front elevation, looking from left to right in Fig. 1, of a pusher block which is hereinafter described, and Fig. 6 is a top View of the same.

Similar numerals refer to throughout the several views.

II designates a stretcher bar to the rear end of which is attached the rear end of a sleevelike fur scarf or pelt I2, which is turned inside out. by means of suitable fastenings, such as nails as at I 2a in Fig. 4.

The front end or head 32 of the scarf or pelt I2 is placed between the base 33 and can 34 of a clamp 33-34, as shown in Fig. 1, in which the rear end of the stretcher bar Il with the greater part lof the scarf or pelt I2 is broken away.

similar parts A yoke 35 is attached to the enlarged middle part of the cap 34 by means of iastenings which are omitted in the drawing, and has attached thereto the lower end of a bolt 36 by means of sleeves 3l and 38 which are secured to the bolt 36 as shown in Figs. 1 and 3; the bolt 36 is threaded as shown.

The bolt 36 passes through an opening in a bridge 39 which is supported by standards 40, and is in engagement with a nut 4| which is mounted on the bridge 39 and is secured thereto.

An arm 42 is secured to the upper end of the bolt 36 and terminates in a pin or handle 43. By turning the bolt 36 in the required direction, by means of the arm 42 and the pin or handle 43, pressure is applied by means of the yoke 35 to the cap 34 of the c-lamp 33-34, thereby securely holding the head end 32 of the fur scarf or pelt I2 in position.

The ends of the cap 34 t between two pairs of guides 44 on said standards 40, to prevent rotati-on of the cap by the bolt 56.

The standards 49 are integral with the rear end of a frame Ill- 20, which has therein an opening 2| extending to the wall 45 at the front end thereof.

The wall 45 has thereon at the front end there of integral therewith a bearing 25 for a journal 24, which has secured thereto at the fro-nt end thereof an arm 2S which terminates in a pin or handle 26a, and has secured thereto rearwardly of the bearing `25 a sleeve 2T, to prevent longitudinal displacement of the journal 24 with relation to the frame I9-20.

The journal 24 has integral therewith and extending rearwardly `therefrom a feedscrew 23 which is in engagement with a feed nut I4 which is integral with a pusher block I3, which has therein a cavity or :groove I5 and two pairs of ilanges I1 and I8, one pairat the top and one pair at the bottom of the block I3.

The pusher block I3 is introduced into the frame I 9-20 through enlarged vertical openings I6a in the top I9 and bottom 20 of the frame ISI-29 and is normally positioned in slots IB in the top I9 and bottom 29 of the frame; the slots I6 are narrower` than the opening IEa, and they dont allow the flanges I'I and I8 to pass therethrough; the flanges I'I are in sliding contact with the top I9 and the flanges I8 are in sliding contact with the bottom 2l] of the frame I9-20.

The stretcher bar I I extends through an opening 2| between the top I9 and bottom 20 of the frame Ill-20 and abuts at the front end IIa thereof against the front wall I3a of the block I3 at the front end of the groove I5.

The opening 2| is wider than the stretcher bar II to provide for bars of different sizes made for scarves or pelts of different widths; and a pair of guides 22 is shown as employed for reducing the width of the space on each side of the bar I I in the opening 2|; guides 22 of different widths may be employed for stretcher bars tl Qf, dilerent sizes.

The front end of the stretcher bar I I is shown as tapered at I la; and the rear ends of the guides` 22 are shown also as tapered, to facilitate the assembling of these parts in the opening-2L,

By turning the arm 26 by means of the pin or handle 26a in the requisite direction thescrew 23 will move the feed nut I4 with the blocll I3 from right to left in Fig. 1; the front wall |31; of the block I3 will press on the end Ila, Qi the stretcher bar II and push the latter rearwardly, thereby stretchingv the fur scarf or pelt I2 which extends. from the clamp 331-34 in Fig. 1 to the pointat which it is. secured' toV thestreteher bar at IfZa, as shown Fig. 41; only a very small partof'thetur scarf'or pelt is shown in Fig. 1, and a larger part is shown in Fig. 4.-

When the stretching operation is` completed the cap 34 of the clamp 33-34 may be raised by turning the arm 42.` in the proper direction, and the head 32 of the fur scarf or pelt is thereby released; the stretcher bar tI-I I'a may then be removed.` from the opening 'ZIfv of the frame lil-20 and another fur scarf or pelt placed on the stretcher bar III to be stretched.

The front Wall 45 of the frame has thereon a pair of` angular braces 28 forengaging-by means of' screw-'sV 28a. the front end of a table or board 29% on- Which the frame I9-20 is mounted and from which it is spaced by means o f spacing bocks or feety and 3I which may be either integral' with the frame I 9-20 as atY 3I` or attached thereto.

The blocks or feet 3l) and 3| enable the flanges Hr of the pusher block I3 to slide on the bottom 20L ofV the frame IS--Z without interferingy with the table 29.

The screw 23 is not overhauling, the operation of stretching may, therefore, be stopped for a While as for inspection of the condition of the pelt or fur scarf.

The device as shown is operated manually; but, i-f desired, the arm 26 may be replaced byone or more pulleys and clutches and operated by means of power supplied by a belt or motor.

Instead of' the feed nut I4 and bearing 45 a stationary nut may be employed and the screw 23 made to travel longitudinally and push the blfock I3, which may be made without the nut I4 on it; the sleeve 21 may then be omitted and the screw 2'3 lowered to the level of the stretcher bar II.

Other variations are possible, and parts of my invention may be used without other parts.

I do not, therefore, restrict myself to the details as shown in the drawing.

I claim as my invention and desire to secure by Letters Patent:
